Optimal pretreatment processes for metal plating on engineering plastics, especially on Nylon-inorganic filler alloy was studied. For Nylon-inorganic filler alloy, adhesion strength between resin surface and metal could be improved by just etching process that eliminate amorphous layer. In the SEM picture and surface roughness measurement, etching treatment was found to make enabled the surface condition very rough and the adhesion strength good. It was also found that the surface condition of plated article and its adhesion strength partly depended upon molding condition of Nylon-inorganic filler alloy. EDS, peaks showed that what kinds of and how much of the metal elements remained on the resin surface after pretreatment processes. Cr did not affect on adsorption of Sn and Pd remarkably.
